Notebook computer battery is the "power source"

Notebook computer battery is the "power source", especially for those who often walk a friend, in addition select models with the ultra-long standby selling point, the timely preparation of a second battery is an urgent task. Meanwhile, the laptop battery is also a consumable, general use in 2012 will be significantly decreased after the performance, coupled with some users usually do not pay attention to battery maintenance work, the Dell latitude d400 Battery performance, as well as the rapid decay of the examples of early retirement are not uncommon. Ran Unfortunately, the growing demand today, the battery market has not subsequently be further standardized. Not only the renovation, the phenomenon of counterfeiting occur from time to time, that is, original manufacturers, even in the same series There is also a man-made obstacles set up. And electoral laptop compared to the choice of the battery does not to mention easy!
A look at parameters
Due to the non-universal laptop battery, consumers must be masters of our own before buying the machine can accept the type of battery at the same time in order to avoid being cheated, in the "see"
Currently, in addition to individual low-end notebooks use nickel-metal hydride batteries, most are used in ordinary lithium-ion batteries, lithium polymer batteries only in part the use of high-grade ultra-thin notebook. Lithium batteries are generally batteries Unit to protect the circuit and capacity for monitoring and communications circuit of several components. From the perspective of the parameters, the battery capacity is an indicator of concern. Now generally 3000 ~ 4500mAh, there are very few with a 6000mAh capacity. In theory the higher values in the same configuration using the longer.
The manufacturer of the laptop battery has a more detailed description, we often can see the "six-core 4400mAh", "4-pin 2200mAh" nominal value such as batteries, over time, we believe that directly determines the capacity of 4400mAh or 2200mAh laptop working hours.
    In fact, we talk about computer power consumption, the total nominal power use, rather than simply current. The battery power should be multiplied by current, voltage to the common 2200mAh, 3.6V batteries, for example, could have used some small way the composition of four batteries in series, their voltage is 14.4V, Capacity 2200mAh. Many 14-inch notebook, you might use 2 and 4 strings of 8-cell hybrid mode, the voltage remains at 14.4V, capacity doubled to reach 4400mAh, to ensure a longer usage time. However, the same is a 2200mAh, 3.6V batteries, if we adopt the 2 and 3 strings of 6 cores hybrid approach, its battery capacity it will still be 4400mAh, voltage down to 10.8V, if we just look at capacity, its use of time should be, and 8 the same cell battery. If you press power, then it 8-cell lithium battery, the power should be 63.36Wh, 6 cores for 47.52Wh, 4 cores for 31.68Wh. If according to this value, the advantages of 8-cell lithium battery can be reflected.
Appearance, the general assembly of the battery shell mold is not original Dell latitude d630 Battery specifications, so loaded notebook computer will appear to take difficult or loose loaded situations; assembly of the battery is not original battery plate production print quality is good, writing and more rough is not clear, in any encounter when buying this kind of "original battery" would not buy. In addition, the renovation of the distinction between products and new battery is still in its electrode wear traces of heavier and therefore does not gloss and new batteries, buy encountered in the so-called "new batteries" do not buy.
Comments:
On the whole, in addition to "6-pin 4400mAh" this parameter, the battery voltage is also a need to know the parameters. From the application point of view, low-voltage large-capacity battery (more parallel, less in series) to ensure the laptop longer standby time, while the battery is almost no additional cost!
Second, weigh the quality
Very often, the quality of both the power and weight proportional, laptop batteries are no exception. As the original battery protection circuit are doing more monitoring in place, the quality is better on batteries, so the weight of the assembly of the battery than the jerry-building is much greater when you buy them by hand Dian Dian, if compared with the original laptop battery light a lot of words Such batteries need to be careful!
As the recent past, Dell, Apple, Sony, Lenovo and other laptop caught fire after another, making the image of the original battery much frustration, but overall the quality of original equipment batteries, or more outstanding. So I believe that choice should be based on a second battery or original products. Of course, the market compatible with many types of cells, some with the original brand notebook chip and the IC design and manufacture of high-quality batteries, not only have all the original battery protection, and stable performance, use of time is relatively long, the actual performance with the original battery is not much difference; but some small workshop production of The quality of the compatibility of the battery is not flattered, and the battery's internal circuit design is extremely simple and the quality of batteries used in more times, and some have even adopted disassemble or brand-name batteries, this battery is compatible with the quality of the natural is not guaranteed; In addition, some laptop batteries inside the original battery failure, a number of business through self-change batteries way for original equipment batteries to obtain a "new life."
However, this time piece of the battery is not the true sense of the original battery, but rather are compatible with the battery, its quality depends largely on how the quality of batteries. So, is compatible with the battery whether it is worth buying, in addition to the price, the key is to see how its quality. For those who are from small workshops compatible battery, even if the prices are a great advantage, not worth buying.
Examples of laptop battery caught fire at home and abroad, mostly due to the dell latitude d620 Battery in use caused by overheating. In other words, the battery in the event of abnormal, many times beyond the normal working state of the heat distribution is a dangerous and allow us to capture the signal source. Under normal circumstances, the battery normally only expressed as micro-heat only. Thus, in our cell for a long time been detected after the test, hand-to-surface, if the feel hot, or hot, stating that the quality of hidden dangers that exist within the battery, do not considering buying.

Weigh weight, measured surface temperature Although it looks simple, but the safety of a battery has a good reveal the role.

3 Measuring Performance

In the computer market and business face to face when you buy laptop battery, the battery testing is an essential part. First, view the focus of the test charge cycles, and second, standby time.
Many people think that laptop battery life calculated according to life expectancy, but in fact not the case, the real factors that play a decisive role should be to fully charge and discharge times. Generally speaking, the international brand of notebook product line will be included in its software, which offers a management tool for the battery. This tool by reading the battery pack inside the intelligent control chip to see such as the use time of battery design capacity, actual capacity and charge-discharge times and other information. Through which users can understand some of the label on the cell surface, do not see the information. Such as the Lenovo ThinkPad, SONY laptop batteries and some other management program, you can view the detailed battery information, if the purchase is a new original equipment batteries, rechargeable batteries should pay attention to whether the frequency is 0 (number of charge cycles up to 2 ~ 3 )
Second is to check the battery capacity. The battery fully charged capacity and design capacity of the comparison, if we find completely filled with a lot of capacity is less than design capacity, indicating a significant reduction in battery performance have not recommended for purchase. If your laptop's battery management program does not have the see the battery fully charged capacity options, such as using software to detect BatteryMon get.

In addition, the compatibility between the battery and original battery there is a big price gap between businesses in order to prevent the battery as the original battery is compatible to sell, in the battery management program should pay particular attention to "producer" and "Part Number" followed by the contents of the display . Generally with original equipment batteries were shown as SONY, SANYO, etc. the standard battery business name and part number, but is compatible with the contents of the battery display is varied, such as PS, or CMP, as well as the IBM-COMPATIBLE or IBM-X3x so.
Comments:
Should be pointed out that the manufacturers nominal standby time is: battery power (WH) / Notebook standby power consumption (W) = Standby time (h) this formula is arrived at. Very difficult to achieve because of physical tests required by the official standby power, so when the Dell inspiron 5160 Battery usage time difference is not very official when the gap between the nominal and the battery can not prove a problem!
Four Questions Service
Laptop batteries are also goods, services, the same can not be ignored, not to mention the price of the current laptop battery is still not cheap!
From a warranty point of view, the battery of the notebook all the components in the shortest warranty period parts, most of the warranty is only 3 months to six months, and even some not even in the warranty of the column, the warranty for up to one year less of the battery with little. Batteries such treatment has not been improved due to be purchased separately, in general, new batteries (including compatible battery) are only eligible for 3 months or 6-month warranty period, if it is second-hand batteries, there will be approximately 7 days to 1 months the warranty period. Therefore, consumers in the payment be sure to ask before the battery warranty period and conditions, do not forget to ask for proof of purchase to the merchant (such as the invoice or a receipt stamped), and let the businesses indicate the battery warranty.
Overall, the market supply of laptop batteries are mainly official website of the brand notebooks and maintenance of points, laptops, and other merchants and online shops. The official website of the brand notebook batteries and maintenance of point of sale positive for the original goods, and users can also enjoy the regular after-sales service, drawback is that prices generally higher; computer businesses in town are mostly stocked with all brand laptop batteries sales, the advantage of much cheaper price than the official website, inadequate quality of service vary widely, there are "Depot" was secretly "changing the core" phenomenon! Against such incidents, Sony, Dell, Asus and other manufacturers of maintenance centers, said there is the problem laptop battery should be replaced as a whole, and should use the original batteries, regular service center does not provide repair (ie change of the "core" to activate other ) business. Recycling batteries will be centrally, there is no "Depot Maintenance" one said. This shows that the value service firms have to buy the regular product!

Taken together, can provide replacement warranty merchants most worthy of consideration!
